Message
Could not verify the server list
Could not verify the server list: what the ForestVPN message cp.catalog_unsigned means, why it appears and what to do about it.
Updated October 11, 2026
The app says: "Couldn't verify the server list."
What it means
The list of locations did not carry ForestVPN's signature, so the app refused to use it.
What to do
Try again. If it keeps happening, try another network.
Why it happens
The app never falls back to an unverified list. A network that rewrites traffic can cause this.
Where you see it
The ForestVPN apps show this message where the step that failed happened. The code is cp.catalog_unsigned.
